Iron Ore Processing
In India, where iron ore processing is one of the major industries, the generation of tailings is estimated to be 10-25 % of the total iron ore mined, amounting to 18 million tons per year (Das et al., 2000). The tailings contain silica in high percentage (40-60 %, from various locations). This makes it a suitable raw material for the ...
